I riccordingito the, construction to be first described, a; bracket or rocker, a (see- Fig. -1)- suitably mounted on a journal concentric with. the shaft Z) ot'the dynamo c, is adapted to carrythe brushholdersid d; and on the said bracket at are mounted suitable contact pieces efg. Thecontacts'e g are in connec tion with one brush h'h and-the contact; f in connection with the-otherbrushil h and the contacts are so arranged that upon the turn ing of the? racket or rockeru through 8, 1 limited are in one direction or the other about its center, appropriate contacts e f or fg are brought into position for switch p111 or blades j"k, as below described, to entert e The friction of'the brushes h on the 'conmru} 4 tator Z is utilized topropel the, rocket-a through the desired are in one dirept'iongoig Y the other according to the direction o frota tion of the -dynamo,and the said rocker; is prevented from turning farther. than is nec: essary by suitable stops m. with this bracket or rocker a a frame or support n is hinged at -0 to a 'fixedbracketp and on the frame n at the-top are mountedthe plugs or connecting p" to, which pieces are ally connect with the appropriatelcontactl.". pieces ef or-fg on the rocker, a'when'thei" frame n is actuated by suitable-rhech The various blades or plugs. and connect are carried conveniently on an plate g. on the frame n and flexible, connec' ing cables (not shown) are providedto-t-ar plate q to the switch board. n a' centrifugal terminals r s t 'u, Figs-11', on the governor to is used in conjunc In conjunction",

leces j 75' before referred f" so placed {asto electri To actuate the lunged franief' governor having arms y 3; provided with prof jections 22 which engage with a projecting flange or-flanges 1 on the said sleeve :0, to transmit the required movement from the governor 'w to the frame n. The centrifugal 5 force of the governor w acts against a spring in the ordinary way, the weight of the gov ernor balls or bobs 2 (which bobs may be adjustable by the set screws 3 along their arms as shown) and the stren th of the spring being suitably proportione to permit of t e governor 'w actuating the framen and making electrical connection when the speed of the ynamo is high enough, and the spring servesto withdraw the frame as the dynamo speed falls below a certain point. "The mechanism genera lly described above ves to connect the dynamo to the outside uit 's fto enable it to supply current in the direction as soon as it is revolving fast 2'0' fenough to produce the necessary electrical energy,"'for as soon as the dynamo revolves inone direction the proper contacts eforf will be brought opposite to the plugs j and and thereafter as soon as the speed is high enough, the governor arms will move sufficiently to cause the sleeve 2: by means of the link connection 4 to mov the frame it so as to insert the said lugs j in n the opposed contacts. The link 4 is pivotally connected to .the sleeve at one end and to a lug 21 on the frame n at the 0th? When the dynamo c s arranged to suppl current to accumulators and lamps connect d thereto, and it is desired to insert a resistance automatically in the lamp circuit, contact pieces 5, 5, are provided suitably fixed on the switch board and a plug orconnecting piece 6 on the pivoted frame it, which serves to short-circuit or reduce theamount of the resistance in circuit when th dynamo is stopped, and insert the resistan e again when the dynamo working, all as will be hereinafter described with reference to a diagram.

.Where the above type of switch is used with a double attery system,-a changeover switch 8 8* s provided the double arm lever 8 of which at 19 on the hinged frame it and have its arms 8 arranged'to be actuated by abutments 9 on the rocker or bracket carrying the contacts. above described in order to oscillate the switch 88 Antifriction rollers 10 are conveniently mounted in the ends of the arms" 1,8. The partial revolution of the rocker is'arranged to bring an abutment 9 opposite one arm 8 of the switch in one directlon' of rotation as seen clearly in Fig. 4 and the same or another abutment opposite the other arm of the switch in the other direction of rotation. In Fig. 4, itis seen that when one abutment 9 and arm 8 are in engagement the opposite arm 8 clears its abutment. As the frame it is moved toward the rocker a the abutment 9 is engaged by one end of one of the arms 8 and causes the switch to turn.

ay conveniently be pivoted.

This serves the purpose of changin over the connections of the batteries at each reversal ofdirection of the dynamo. 'So-called carbon breaks as is well'kn'own may be suitably employed to make contact before and break contact after the knives of the switches make and break contact, to prevent the spark, which occurs on breaking circuit, from burning the metal contact pieces.

As seen best in Fig. .3 the contacts e and g are arranged so that when in the engaging position they are. vertical whereas the contact f may be'V shaped, being composed of two parts each of which when in engaging position is vertical and'par allel with its corresponding member 6 or blades or plugs 7' 7c to be lying between e and the left hand branch of the contact f as seen in Fig. 4; when the dynamo decreases its speed suiiiciently the blades 7' 7c are withdrawn and upon reversal of rotation, the right hand branch of the contact f will be brought opposite j and the contact 9 opposite lc, so that it can be arranged for Ye, for instance, to always be negative.

Fig. 5 shows a slightly dii'lerent construction with the parts in the position which they occupy when the requisite speed has been attained. in this construction the arms 8 are fixed to the pivot of the switch beneath the latter. be seen that the switch brushes or blades 8, on the side from which the parts are viewed have been moved to make contact with the contact plates .11 and 38, while those on the other side have been moved outward over the plates 39 and 12 all as will be more clearly understood after the description given below of the corresponding parts seen in Fig. 10.

According to the modification shown in Figs. 6 and 7, the bracket a carries only two contacts 13 and 14 in place of the three e f g I Fig. 1, and three brush contacts 15, 16, 17 are carried by the hinged frame it in place of the two plug contacts 7' 7: Fig. 1; the brushes 15, 16, 17 are'each provided with a carbon break 18. Thus the two contacts l3and 14 upon the rocking of the part a will be brought opposite the appropriate brushes 15, 16 or 16,

17 as the case may be preparatory to the cir-' cuits being closed by the governor upon the attainment of asuflicient speed. The changeover'switch marked 8 8 in Fig. 1, also is modified and is now of the plug type as shown, the plugs being carried one at each end of the oscillatory bar 20. The lug 21 on the frame 7L projects farther toward the governor in this constructionand the link 4 is say of triangular form having a spring 22 around a pin 23 and one end of the spring extended and taking over the pivot pin 24 of the link 4 or the ends of the spring may take over both the pin 24 and the pin 25 The pin 24 is formed with a notch into which the g. Supposing the in this position it will ofthe pins spring end takes thereby holding the pin in place without the aid of a lincli pin or lock nut. The end of the pin is suitably rounded or beveled so as to lift the spring end when the pin is pushed in. The relative positions 24' and 25 and the length of the link 4 have been so calculated in this modification that when the brushes have been moved on to their contacts 13, 14 the brushes 15, 16 and 17 shall not be rndulyiiexed and thus set up considerable friction between the flange 1 and the projections z 2 (which latter are preferably of wood), for it will be seen that as the, sleeve 1 1S moved toward the right hand in 6, the pin 25 comes under the pin 24-as indicated by the dotted circles so that at about this point the greater part of the .pressure transmitted by the link 4 will be radially through the switch 32 and not axially of the shaft.

Instead of the plate 9 being approximately vertical, as in the preceding constructions, the same may be arranged horizontally on the rectal framing n, as seen in Figs. 8 and Sit ese figures show on the base plate q an arrangement of three brushes 15, 16, 17 as in Figs. 6 and 7, and these brushes may if desired have a carbon break as m the earlier figures.

All the parts are in this construction carried upon the upper face of the plate qincluding the oscillatory bar anc the switch parts 7, 7. if desired the arms 8 might be made, in one with the bani 0 or as shown the two parts may be connected with" insulation 20 between but of course the arrangement of switch contacts 7 7 bar 20 and arms 8 can be the same as in Figs. (5 and 7.

It is necessary when the three contacts 15, 16 and 17 are, employed on the frame n to always cause the field magnet winding 34 to be connected in a particular manner hereinafter indicated; therefore the bar 20 is furnished with a rubbing spring contact 2O which connects across from the plate 35, (which plate is connected with :tl e field. winding 34 {so for instance the (lia -ramFig. 1. 1) to the p ate 37 in connection the brush 17 as shown when the switch to the brush 15 and from the plate 35 to the plate 36 in connection with the brush 15 whenconnection is made between the arm 8 and contact 7 belonging to the brush 17 thus the winding 34 is always in parallel with the battery being charged, as well as with the lamps and their resistance as will hereinafter appear. The action of those constructions embodying threccontacts on the rocker will be well 'nderstood by reference to 10 wherein the terminal marked 25 is connected bye. condoctor 26 to a c ntact or connection is which will always be negative and the terminal t is therefore connected as shown to the negative tenninalwn the rhcostat or split resistance 29 of knowntype. The terminals r and u are 1 conductors 46 and 26.

or'connections 38, 3-9-which are always posi tive (for the brush switch '8 takespp either the position in full black lines or th sijtion in dotted lines) and these terminals 1 a d u are therefore connected to the end terminals 41 and 43 of the rheostat '29. The terminal 3 is by the conductor 29 coniicctedito the plate 12 which is connected alternately to the contacts 38 or 39 by the oscillatory switch 8, the plate '12 being'connected with the lamp terminal 45 mounted on the rheostat board which terminal is connected with the lamps 30 as shown, the opposite terminals of the lamps being connects-.1 to the negative pole of the battery 31, which is preferably of the split type shown. In addition to What has been described there a switch 32 in the field winding 34 of the dynamo so that the field winding 34 is only energized upon the attainment of the predetermined speed. There may be a fuse 33 between the negative In- Fig. 10 the plug receives cur-rent above described and electrifies the plate 11 from which plate the following branch circuits run to the negative terminal 40 on the rheos-tat 29 viz. (a) through switch field winding 34 (b).switch 8*, plate 38, wire 27, terminal r, right hand terminal 41 on rheostat 29, upper )art of battery 31, an l wire 42 (0) left hand brush of switch 8, plate 38, wire 27,1termi al r, terminal 41, resistance 29, terminal 43, wire 44 to terminal u, wire 28, plate 39, cpwsite brush of switch 8,

plate 12, wire 29 terminal 8, lights terminal 45, lamps 30 and wire 42 (cl) loft handbrush of switch 8 plate 38, wire 27, terminal 1',

terminal 41, resistance 29, terminal '43 lower part of battery 31 and wire 42. From the negative terminal 46 the common return is by way of wire 46, terminal 16 wire 2 6, and negative plug 7:. Thus the field winding 3 half battery without resistance, lamps with resistance and half battery with resistance are all in parallel.

WVhcn the dynamo is not being driven fast enough for the governordeviceto rock the frame it to close the above circuits, then the switch device 5, 6 is closed and short circuits the larger part of the resistance 29 and the circuit will be (in the position of the parts seen in I ig 10 for instance) :-from the upper part of the battery 31, to terminal 41, to

switch 5, 6, through smaller part of resistance to terminal 43, by wire 44 to terminal 2t, wire 28, right hand brush of switch 8*, wire 29', terminal 8, terminal 45, through lamps back to battery from the lower half of the battery the current passes direct to terminal 43 and there joins the current from the other battery part. he same circuits are ,made when the'batte-ry reverses as will be well understood. f

In It ig. 11 which represents the construca 26 is in connection with the middle contact not workin are the same as in Fi 10.

circuit terminal contacts cooperative with stops for imiting the movement in either ditions comprising two contacts on the rocker l a and three on the pivot-ed frame a, the wire 16 which is always, say, negative and in one direction of rotation the current will be received from the contact 15 through the plate 36 and wire 27 while in the opposite direction it will received from the brush 17 plate 37 and through the wire 23. In the in st fiS8 the circuits from the plate 36 to the negative terminal 40 on the resistance board are as follows :(a) through contact 20 to plate 35, switch 32, field winding 34, ((2) wire 27, terminal r to terminal 41, upper part of battery and wire 42, (0) wire 27, terminal 1 to' terminal 41, resistance 29, terminal 43 to terminal a, wire 28, contact 7, barfZO, wire29, terminal 8, to terminal 45,.lamps 30, wire 12 ((1) wire 27, terminal 1 to terminal 41, resistance 29, terminal 43, lower part of battery wire 12. li rom the terminal 40 the current passes by Wire 16, fuse 33, terminal t and wire 26 to the negative brush 16. When the dynamo is reversed the current arrives by way of plate 37 and wire 28 and. the circuits are (a) as before (6) wire 28, terminal a to terminal 43, lower part of battery (0) wire 28, ter" minal a, wire 44 to terminal 43, resistance 29, terminal 41 to terminal 1', wire 27, contact 7, bar 20, wire 29, terminal 8, terminal 45, lamps 30 ((1) wire 28, terminal a to terminal 43, resistance 29, terminal 41, upper part of battery.
